Description

Verfahren zum Reinigen und Verdichten von Rohgas Bei der Verdichtung von ungereinigtem Rohgas entstehen in den Verdichtern derart starke Ablagerungen, daß es praktisch nicht möglich ist, dass Gas in ungereinigtem Zustand den Verdichtern zuzuführen. Das Gas muß daher vor der Versdichtung durch eine Reinigungsanlage geleitet werden. Da die Reinigung vor der Verdichtung, also unter Atmosphärendruck, vorgenommen wird, sind umfangreiche und raumbeanspruchende Reinigungsanlagen erforderlich.Process for cleaning and compressing raw gas During compression of unpurified raw gas, such strong deposits form in the compressors, that it is practically not possible for gas in an uncleaned state to enter the compressors to feed. The gas must therefore be passed through a cleaning system prior to sealing will. Since the cleaning is carried out before the compression, i.e. under atmospheric pressure extensive and space-consuming cleaning systems are required.

Durch die Erfindung soll es möglich werden, ungereinigtes, nur von etwaigen Bestandteilen befreites Rohgas, wie es in den Kokereien und aus Generatoren anfällt, anzusaugen und zu verdichten.The invention should make it possible to unpurified, only from raw gas freed from any components, as it is in the coking plants and from generators accrues to suck in and compress.

Die bisher bekannten Verfahren ordnen die Reinigung der Rohgase vor der Verdichtung oder bei ganz gering erhöhtem Druck an.The previously known methods pre-arrange the cleaning of the raw gases the compression or at very slightly increased pressure.

Im Gegensatz hierzu besteht das erfindungsgemäße Verfahren darin, daß das ungereinigte Rohgas nach oder unter Zusetzung eines Lösungsmittels, z. B. Benzol, verdichtet und dann das verdichtete Gas in an sich bekannter Weise gereinigt wird. Das Lösungsmittel kann in die einzelnen Verdichterstufen eingespritzt werden. Die eingespritzte Menge wird entsprechend,dem Druck und der Temperatur in den einzelnen Verdichterstufen derart bemessen, daß der Sättigungszustand an keiner Stelle überschritten wird. Der entstehende Lösungsmitteldampf verhütet die festen Ablagerungen im Verdichter.In contrast to this, the method according to the invention consists in that the unpurified raw gas after or with the addition of a solvent, eg. B. Benzene, compressed and then the compressed gas is purified in a manner known per se will. The solvent can be injected into the individual compressor stages. The amount injected will be according to the pressure and temperature in the individual Dimension the compressor stages in such a way that the saturation state is not exceeded at any point will. The resulting solvent vapor prevents the solid deposits in the compressor.

Durch die Erfindung ist es möglich, die bisher vor dein Verdichten durchgeführte Gasreinigung fortzulassen und sie dem Verdichtungsvorgang nachzuschalten. Da die Reinigung des Gases unter höherem Druck, also bei kleinerem Volumen, stattfindet, erhält die Reinigungsanlage wesentlich kleinere Abmessungen.Thanks to the invention, it is possible to compress the previously before your to omit performed gas cleaning and to connect it after the compression process. Since the cleaning of the gas takes place under higher pressure, i.e. with a smaller volume, the cleaning system gets much smaller dimensions.

Das eingespritzte Lösungsmittel kann in einer nachgeschalteten Wäscherei zurückgewonnen werden. Das bedingt jedoch keinen Mehraufwand, da nach dem bisherigen Verfahren ,dem Verdichten ebenfalls eine Benzolwäsche folgte. Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß bei der Reinigung unter Druck mit einer wesentlich stärkeren Reaktion der Lösungsmittel zu rechnen ist, so daß noch eine Einsparung an Lösungsmitteln eintreten wird.The injected solvent can be used in a downstream laundry to be recovered. However, this does not require any additional effort, since after the previous one Process also followed by a benzene wash for compaction. Another advantage of the method according to the invention consists in that when cleaning under pressure with a much stronger reaction of the solvent is to be expected, so that there will still be a saving in solvents.
